# wukong User Guide

## Introduction

wukong is a built-in command line tool that implements application stability test capabilities such as random event injection, component injection, exception capture, report generation, and data traversal of abilities. This tool allows you to conduct stability tests on the system or applications by simulating user behavior. wukong provides three types of testing: random testing, special testing, and focus testing.

In random testing, test inputs are generated randomly. Available features include shell startup, whole application startup, multiple injection modes, random seeds setting, run log printing, and report generation.

In special testing, specific application components are tested. Available features include shell startup, sequential traversal and screenshot, sleep and wakeup test, recording and playback, run log printing, and report generation.

In focus testing, specific components are injected. Available features include shell startup, device application startup, multiple injection modes, random seed setting, focus component type setting, component injection times setting, run log printing, and report generation.

## Principles

The following figure shows the wukong component architecture and the responsibilities of sub-modules. 
![Alternate text](figures/wukongRandomTestFlow.png)

- Command line parsing: Obtain and parse parameters using commands.
- Operating environment management: Initialize the overall operating environment of wukong using commands.
- System API management: Check and obtain the specified mgr, and register the callback function of the Faultlogger for the controller and DFX.
- Random event generation: Use the **random** function to generate a sequence of random numbers with the specified seed value to generate an event.
- Event injection: Inject events of supported types to the system. This feature depends on the window, multi-mode, and security subsystems.
- Exception capture and processing and report generation: Obtain exception information with the DFX subsystem during application running, record log, and generate reports.

## Constraints

1. The wukong tool is built in the system since API version 9.

2. In API versions earlier than 9, you need to build the tool and push it to the target device. The procedure is as follows:

   ```bash
   // Build code.
   ./build.sh --product-name rk3568 --build-target wukong

   // Push code.
   hdc shell mount -o rw,remount /
   hdc file send wukong /
   hdc shell chmod a+x /wukong
   hdc shell mv /wukong /bin/
   ```

3. When the PC is connected to one or more target devices, you can run test commands.

4. Enter the shell mode before running any command.

## Viewing the Test Result

### Test Result Output Path

After the test commands are executed, the test result is automatically generated. You can obtain the test result in the following directory:

- For DevEco Studio versions earlier than September 22, 2022: /data/local/wukong/report/xxxxxxxx_xxxxxx/
- For DevEco Studio versions later than September 22, 2022: /data/local/tmp/wukong/report/xxxxxxxx_xxxxxx/

### Test Report Directories

| Type                                | Description              |
| ------------------------------------ | ------------------ |
| exception/                           | Stores exception files generated during the test.|
| screenshot/                          | Stores the screenshots of the test traversal. |
| wukong_report.csv                    | Stores the test report summary.      |
| wukong.log                | Indicates the test operation history.      |

### Viewing Operation Logs

You can run the hdc command to obtain logs to the local host and view the operation history.

```bash
// The path of the wukong.log file is as follows:
/data/local/tmp/wukong/report/xxxxxxxx_xxxxxx/wukong.log

// To view the directory of the wukong test report, run the following command:
# cd /data/local/tmp/wukong/report/20170805_170053
# ls
data.js  exception  wukong.log  wukong_report.csv

// Open the shell and run hdc file recv to obtain wukong logs.
